Spring Data JPA: Named method without JpaRepository

Question

I would like to have a single-method interface with the method:

boolean existsByStrAndStatus(String str, Character status);

and have it work as-is as a named method. However, all the examples I've seen of this inherit from JpaRepository and I don't want to inherit from this interface as any implementation that I write (for testing purposes) also need to inherit all the built-in convenience methods that JpaRepository provide such as findAll, flush etc.. I am well aware of mocking frameworks, but I am looking for a solution that doesn't involve using for example Mockito.

Is there an alternative to JpaRepository where I can still @Autowire this repository as I see fit, but if I need to write an implementation I only need to implement my own method?

Answer 1

I think you should create custom implementation of your interface:

class TestRepository implements Repository

Which will implement only your custom method and rest leave unimplemented. Then you can use it in your tests.
